It's possible to set the Data Type of a site property to Identifier of a static entity, which is great, since most of our static entities have a text Identifier. However, for some inexplicable reason, the Default Value options is made inaccessible as soon as an Identifier is selected. Why? It would be easy to allow selecting one of the static values from a dropdown. Please OS, add this, since now I'm having to make the type Text and cast it etc.
